DOOR-CLOSER.

Specification of Letters Patent. I Pate nt ed Oct. 30,1917.

Application filed March 21, 1916. Serial N 'o. 85,583.

To (ZZZ whom it may concern:

Be it known that I, ALBERT T. 'LOFTSGA AR DEN, citizen of the UnitedStates, residing at Powell, in the county of Park and State of Wyoming,have invented certain new and useful Improvements in Door-Closers, ofwhich the following is a specification.

My present invention has to do" with sprang-actuated door-closingdevices; and.

generic combination and specific" embodiments hereinafter described anddefinitely;

pointed out in the claims appended.

In the accompanying drawings which are hereby made a part hereof:

Figure 1 is a perspective of the preferred form of my invention.

Fig. 2 is a horizontal section through the door and door casing andshowing the improved device in plan.

Fig. 3 is a transverse section taken on the line 33 of Fig. 2 andshowing the pivotal connection between the swinging arms of the device.

Referring by numeral to the drawings:

1 is the side stile of a door frame, and 2, a door, hinged to the stilein the ordinary or any other suitable manner, as shown in Fig. 1.

In furtherance of my invention thestile 1 and door 2 are provided ontheir faces with brackets 4.

To the stile bracket 4 is hinged one end of the arcuate,horizontally-swinging arm 5.

The said arm 5 is provided adjacent to its middle with a loop-shapedoutwardly-extending portion 6, and its free end 5" is arrangedcomparatively near the outer side or face of the door 2 as best shown inFig. 2; the said free end being preferably provided with an upstandingapertured lug 7.

The bracket 4 on the face of the door 2 serves for the pivotalconnection of a second horizontally-swinging arm 8. This arm 8 is alsoof general arcuate form, and is arranged with its free end 8 adjacentto'the tion of the arms each to the other.

face of the door- Near its middle the 8 is provided with an outwardlyextending loop 9 which straddles theportion f the door arm 5 and ispivotally'connected thereto, preferably through the medium of a pintle10 which enables each arm to swing onthe other; It willbe apparent thatthis arrangement disposes the I arm portions. 8" I and: 9 at the samesideof thedoor closer considered as a whole which is. desirable inasmuchas it promotes free working of the sprmg that will now be described;Itawill also be. apparent that the free end of the armportion 8" is"shaped as ahook, Fig. ,1, this'rbeing materially advantageous inasmuchas the spring: can be readily unhooked, thereby allowing the doorto beleft open when desired;

Interposed between the free ends of the swinging arms 5 and Sandconnected therewith is a retractile spring 11 equipped with means 12 forregulating the tension thereof. In the preferred arrangement, the spring11 at one end is connected directly to the end 8 of the arm 8, and theopposite end of the spring is coiled back of a nut 13 which incombination with a bolt 14 forms the tension-regulating means for thespring.

The said bolt 14 extends through the aperture of the lug 7 and has akerfed head back of said lug, and hence it will be understood thatturning of the bolt will be attended by tightening or loosening of thespring according to the direction in which the bolt is turned.

Manifestly on opening of the door 2, the

free ends of the arms 5 and 8 will be moved away from each other, andthe spring will be stretched or put under tension. Consequently whenthe'door is released and. the 9 spring contracts to its normal state,the spring will operate through the arms 5 and 8 to close the door, andthis promptly and powerfully becauseof the considerable leverage thespring is enabled to exert.

It will be appreciated from the foregoing that the embodiment thus farspecifically described is simple and strong, and is well adapted .to'withstand shocks and rough usage as well as exposure to the weather. Iwould also direct attention to the fact that in said embodiment theretractile spring is connected to the portion of one swinging arm thatextends beyond the pivotal connechaving a free end disposed adjacent tothe face of the door and also having an outwardly-extending loop-shapedportion adjaeentito its middle, an arcuate, horizontallyswingingarmpivoted to the door bracket and having .a :free end adjacent to theface of thepdoiors and also having an outwardly extending loopstraddling and pivotally con- ;nected'. to the outwardly-extending loopshapedportion of the firstnamed arm, and :a retractile: springextendingbetween and 20 connectedwith'vthe free ends'of said arms.,IniaLdoor-closmg device, the combinationof a door-frame, a doorlnngedthereto,

ally connected at an intermediate point of its length with theintermediate portion of the first-named arm and having a free endadjacent to the face of-the door, and a retractile spring extendingbetween and connected with the free ends of said arms and inclosedbetween the arms and the face of the door in approximate parallelrelation to the latter.
